Grim, you are being very much a Killjoy, you disagree, big deal, you don't have to constantly whine back about and Icicle, you're doing the same. Although I do Agree with you.
Anyways, in my opinion, if one were to combine shock and Ice it may work in the way that the Lightning may freeze the opponent on contact. Idk, just a thought.
And I'd combine Inferno and Ice to create a water attack. Seeing fire could melt ice turning it into water which will cancel out the flame.
And here's a list of other combinations
Ice + Vortex = Hailstorm
Fire + Vortex = A fire Tornado
Shock + Vortex = A storm
Blades + Ice = Blades that will freeze you upon Impalement
Shock + Blades = Electrocution upon impalement
Force Push + Fire = Might surround you in a fire forcefield
Those are all just thoughts.
